Help EVDO to LTE Problem on Thunderbolt

[Teegunn]

Buddy of mine works for VZ and he said the issue is the LTE switchover originally, but at this point they are being told that issue is fixed. Not really new news, but if verifies for me that the LTE handoff was at least a major issue.

You are correct. I seriously jumped the gun and made some mistakes in my post. The TB does indeed use both the Snapdragon SoC and MDM9600 chipset (MDM is not a single chip just to be clear - it is 6 chips - hence "chipset"). However, the MDM9600 is much like the Snapdragon in that it is a evolutionary step in a long line of similar products and absolutely is not at all a "first of its kind" nor "first generation". In that the OP is still incorrect.

I still also contend that any link between problems with a modem product using the same chipset and the TB is HIGHLY speculative at best.

Anyway, sorry to the OP and to all.

What other chip supports LTE all CDMA and GSM technologies combined and it's backwards compatable with all the legacy 2G and 2.5G? Thats why it's first of it's kind. I don't mind engaging in constructive debate, but you're mixing CPU with rf chip...
I know you didn't have bad intention so it's all good.

The only addition to the chip set is LTE and that is not even at new frequencies. Hence I call it an evolutionary chip set not revolutionary and is definitely not a "first generation" chip set. It builds on the backs of all of the prior and very similar MDM chip sets.

Point is the chip covers a lot of stuff, but all moot unless programmed along with the device FW to use everything (and carrier towers). The only thing this chip is good for is the OEMs since they can buy more volume of one chip. Less components to manage and better price breaks with mass purchase.

Consumers see diddly, unless CDMA and GSM were all one company..... If Sprint buys Tmo, might help for them

It's not the only addition. It's the first chip with LTE capability that's fully backwards compatible with legacy GSM/CDMA modes.
Anyway, it's useless to waste time on this matter, let's stay on subject.

..... What was the subject?

LOL! Exactly

The MSM8655 has the MDM9600 integrated into it. While the MDM9600 can be sold as a standalone modem chipset, MSM8655 integrates the MDM9600 with the Scorpion application processor and is sold as a single chipset.

I don't really think so. The MSM8655 is an SoC device, not its own chipset -

Mobile Processors | Snapdragon | Qualcomm

Qualcomm News and Events - Press Releases - Qualcomm?s Snapdragon Processor and LTE Modem Power Connectivity Devices on Verizon Wireless? New 4G LTE Network

The difference between the two MSM8x55 devices is which radio(s) are capable of being controlled - same as it was for the 8x50.

Lots more info at QDevNet - Home | QDevNet is the Qualcomm Developer Network offering tools, SDKs, and other resources for mobile application development and optimization on Android and Windows Phone. also.

As for the original subject - there's a good point there, but it is speculation until we see final results. The development tools were available to prevent the issue and Pantech != HTC -- so only time will tell.

Can't the terms 'chipset' and 'SoC' be used interchangeably?

 

[EarlyMon]

SoC means a system on (a) chip - it's basically a slice of something that would occur on a circuit board that's so well-defined, the whole thing can be built onto a huge mega-chip.

In the case of the mobile processors, there are a LOT of cores there - cpu, gpu, dsp, image processors, clocks, etc, etc.

A chipset is a group of chips designed to specifically in concert with each other. Originally, these gained public recognition to mostly include clocks and address decoders and other glue logic specific to some processors.

So - if I were take a processor, related chipset and the circuit board necessary to play all of that together and condense into a single a chip - that would result in an SoC and would no longer be a chipset.

Now - the SoC in this case is targeted for mobile use and now we need some radios, modems, etc, that we can predict and standardize - they form the new chipset around that SoC.

edit and ps -

chipset - a collection of chips serving support functions
SoC - not a bunch of chips hidden in a black package - a mega-chip, formerly made of multiple chips

Just wrong.

Just to prove that actually you are wrong, here is a qualcomm's internal MDM6600 spec sheet.
MDM9600 is even better as in addition to the same bands as MDM6600 adds support to LTE and DC-HSPA+. http://www.qualcomm.com/news/releas...ls-new-roadmap-gobi-connectivity-technologies
